OS X 10.11 pyenv install [resolved]

[impressiver]

This isn't an issue so much as a note to anyone else who might run into something similar. I tried installing python 2.7.10 on OS X 10.11 beta and ran into an old problem ( #263 ). The end of the Python install logs were less than helpful:

...
if test "xno" != "xno"  ; then \
        case no in \
            upgrade) ensurepip="--upgrade" ;; \
            install|*) ensurepip="" ;; \
        esac; \
         ./python.exe -E -m ensurepip \
            $ensurepip --root=/ ; \
    fi

That was the end of it. Not much to go on. Then I found and ran pyenv doctor, which was nice enough to spit out a much more illuminating error message before it pooched:

...

(HINT: it's the part about OpenSSL, there's a note about it on that link)

The wiki entry does in fact include everything required to fix the problem, but it's not all in the same copy-pasteable block. After a few tries, I stumbled on the magic combo:

CFLAGS="-I$(xcrun --show-sdk-path)/usr/include -I$(brew --prefix openssl)/include" LDFLAGS="-L$(brew --prefix openssl)/lib" pyenv install -v 2.7.10

(sub 2.7.10 for whatever version you want to install)

Combining the xcrun and openssl include/lib paths is like summoning Captain Python.

If you install OpenSSL from hombrew, since Apple no longer ships the OpenSSL headers, you could run:

brew link --force openssl

[yyuu]

Actually python-build is already configured to find openssl from brew's prefix if it is available. With this code, you don't have to do brew link --force openssl.

https://github.com/yyuu/pyenv/blob/43eb33e9295816a79858f5174ae487504476a489/plugins/python-build/bin/python-build#L1265

@impressiver I suspect you didn't have Command Line Tools for Xcode at that time and you also didn't have openssl headers in /usr/include/openssl. I'm not sure if Command Line Tools for Xcode is available for 10.11 Beta, but apparently pyenv needs openssl headeres in either /usr/include or brew's prefix.

The summoning is required if your system doesn't have proper installation of Command Line Tools for Xcode and doesn't have brew's openssl. If you prefer simpler way, I'd recommend you to install brew and brew install openssl. It also requires Command Line Tools for Xcode, though.

Anyway, if you find something is missing on the Wiki documentations, feel free to update the document as need. Everyone can edit.

[digitalresistor]

Unfortunately it seems that unless I do as I mentioned above (brew link --force openssl) the builds will not pick up the OpenSSL installed as a keg:

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include

The build correctly picks up OpenSSL if I brew link --force openssl

[yyuu]

@bertjwregeer Umm. Sorry my bad. The use_homebrew_openssl will never be invoked with current pyenv impl. I'll try to fix the python-build to use it. Thanks for letting me know.

[yyuu]

@bertjwregeer e52ed97 should install use brew's openssl if it's available, or install openssl from source. Can you give it a try?

[digitalresistor]

Yup, will give it a try when I get back from work.

[yyuu]

I merged ^ changes into master branch. With latest master, python-build should build & install openssl if it is not available via both Xcode and Homebrew. This should solve the issue of missing OpenSSL library intrinsically.

Feel free to reopen if you still have some issues.

[geryit]

Had the same issue,
$ xcode-select --install
fixed it
